Section 1: Hinging the Ailerons
Right wing panel with aileron and hinges
Left wing panel with aileron and hinges
Instant thin CA glue
CA remover/debonder
Parts Needed Tools and Adhesives Needed
Note: The control surfaces, including the ailerons,
elevators, and rudder, come with the hinges installed, but
the hinges are not glued in place. It is imperative that you
properly adhere the hinges and ailerons in place per the
steps that follow using a high-quality thin CA glue.
Step 1. Carefully remove the aileron from one of the wing
panels. Note the position of the hinges. The Taylorcraft comes
with high-quality CA-type hinges.
Step 2. Remove each hinge from the wing panel and place a
T-pin in the center of each hinge. Slide each hinge into the wing
panel until the T-pin is snug against the wing.
Step 3. Slide the aileron onto the wing until there is only a
slight gap. The hinge is now centered on the wing panel and
aileron. Remove the T-pin and snug the aileron against the wing
panel. This will ensure that the hinges are centered.
Step 4. Deflect the aileron and completely saturate the hinge
with thin CA glue. The aileron's front surface should lightly
contact the wing during this procedure. When the hinge is glued
in place, a 1/32" gap or less will be maintained throughout the
length of the aileron. The hinge is constructed of a special
material that allows the CA to wick or penetrate and distribute
throughout the hinge, securely bonding it to the wood structure.
Step 5. Turn the wing panel over and deflect the aileron in the
opposite direction from the opposite side. Apply thin CA glue to
each aileron hinge, making sure that the CA penetrates into both
the aileron and the wing.

Step 6. Using CA remover/debonder and a paper towel,
remove any excess CA glue that may have accumulated on the
wing or in the aileron hinge area.
Step 7. Repeat this process with the other wing panel, securely
hinging the aileron in place.
Step 8. After both ailerons are securely hinged, firmly grasp
the wing and aileron and check that the hinges are securely
glued and cannot be pulled out. Do this by applying medium
pressure, trying to separate the aileron from the wing. Use
caution not to crush the wing structure.
Note: Work the aileron up and down several times to
"work in" the hinges and check for proper movement.

Section 2: Joining the Wing Halves
Right/left wing panels
Wing joiner
30-minute epoxy
Epoxy brush
Masking tape
Hobby knife
Rubbing alcohol
Paper towels
Parts Needed Tools and Adhesives Needed
Step 1. Locate the wing joiner. Using the ruler, determine the
center of the joiner and mark it with a pencil.
Step 2. Trial fit the wing joiner into one of the wing panels. It
should insert smoothly up to the centerline marked in Step 1.
Now slide the other wing panel onto the wing joiner until the
wing panels meet. If the fit is overly tight, it may be necessary
to sand the wing joiner. Check to make sure the alignment of
the wing is accurate.
Step 3. The wing has 0° dihedral. Place the wing on a large
flat surface with both wing panels resting on the flat surface.
If necessary, sand the wing joiner until this is achieved. There
should be no gap in the wing center.
Step 4. Separate the wing halves and remove the wing joiner.
Once you’re satisfied with the trial fit of the wing panels, you can
prepare to epoxy the wing panels together.
Note: Use the plastic wing covers as a means of keeping
epoxy from smearing on the wings. Slip one on each panel
and use masking tape to hold in place.
Step 5. Mix an ample amount of 30-minute epoxy. Have some
wax paper handy to prevent epoxy from dripping on your
workbench top.
Note: It is extremely important to use plenty of epoxy.

Step 6. Place one wing half right-side up on a flat work
surface. Use a scrap piece of wood or an epoxy brush and smear
a generous amount of epoxy into the wing joiner cavity in the
wing panel.
Step 7. Coat one half of the wing brace with epoxy on all sides,
up to the pencil line drawn in Step 1. Install the epoxy coated
half of the wing brace into the wing joiner cavity of the wing
panel, up to the centerline. Use rubbing alcohol and a paper
towel to clean up any excess epoxy.
Step 8. Apply a generous amount of epoxy into the wing brace
cavity of the other wing panel.
Note: You will need to mix additional epoxy to complete
the wing joining process.
Step 9. Next, apply epoxy to all sides of the exposed area of the
wing joiner and uniformly coat both wing roots with epoxy.

Step 10. Carefully slide the two wing halves together and
firmly press them together, allowing the excess epoxy to run out.
There should not be any gap in the wing halves. Also, check to
make sure the wing panels align properly. Wipe any excess
epoxy away with rubbing alcohol and a paper towel. The plastic
wing bags can be removed at this time.
Step 11. Apply masking tape at the wing joint to hold the wing
halves together securely. Place the wing top-side up on a flat
surface. Apply more masking tape to the wing center joint. Make
sure the wing halves are still properly aligned. Allow the wing
joint epoxy to cure completely (overnight).
Note: It is helpful to use wax paper underneath the wing
center while the epoxy is curing so any excess epoxy will
not adhere to the work area surface.
Step 12. After the wing center joint is cured completely,
remove the masking tape.
Note: If there is any gap between the wing halves, fill
with epoxy.
Procedures for mounting the wing to the fuselage will be
presented in Section 5.

Step 1. Locate the servo openings in the bottom of each of the
wing halves. Use a sharp hobby knife to trim away the covering
over the openings.
Step 2. Install the recommended servo hardware supplied with
your radio system onto your servos (grommets and eyelets).
Install a servo extension lead to the servo as well. Secure the
connectors with by tying them in a knot and use electrical tape
to secure in place and prevent opening in flight.
Hint: It is always a good idea to secure the servo
connectors and servo extension together to prevent the
wires from becoming unplugged inside the wing.
Step 3. Trial fit the servo into the servo opening. Some
trimming may be required, depending on the type of servo
installed.
Note: We have orientated the servo so the servo arm is
closer to the trailing edge of the wing.
Step 4. With the servo in place, mark the location of the servo
screws that are used to mount the servo to the plywood rail
inside the servo opening in each wing half.

13
Step 5. Using a 1/16" drill bit, drill the servo screw locations
marked in Step 4.
Step 6. Before mounting the servo, it would be wise to run the
servo lead and extension through the wing and out the opening
provided for each at the wing center on the top of the wing. Turn
the wing so you can see the root rib. Look carefully for a circular
opening near the root of the wing, in each wing panel. Trim away
the covering to expose the opening. Use a sharp hobby knife to
remove the covering over each opening using caution not to cut
into the wing sheeting.
Step 7. We suggest the following simple method to thread the
servo lead and extension through the wing servo opening. Attach
a weight (small nut) to a length of string and drop it through the
servo lead opening in the wing and allow it to exit through the
servo opening in the bottom of the wing.
Step 8. Once you have the string threaded through the wing, tie
it to the servo lead extension connector. Carefully thread the
servo wire extension through the wing.
Step 9. To prevent the extension from falling back inside the
wing, use masking tape to temporarily hold it in place by taping
the extension to the top of the wing.
Step 10. Secure the servo to the wing using the screws
provided with your radio.
Step 11. Repeat the procedure for the other servo.
Note: If using a non-computer radio, it will be necessary
to use a Y-harness to connect both aileron servos to the
aileron channel.

Step 1. Turn the wing upside down on a flat surface. From the
aileron servo control arm that is attached to your servo (if it is
not attached, do so now), use a felt-tipped pen and ruler to mark
the location of the servo horn, directly in-line with the servo
control arm as shown. Note the portion of the servo arm we use
is the one pointing toward the wingtip. Remember to locate the
control horn so the clevis holes are directly above the hinge line
of the aileron.
Step 2. Place the center of the control horn on the aileron at the
mark made in the previous step. Mark the hole positions of the
control horn.
(Step 2 photo)
Step 3. Remove the control horn and drill two 1/16" holes
through the aileron as marked. The trailing edge of the aileron
should be in line with the rest of the wing. Drill straight down at
a 90-degree angle to the flat surface.
Step 4. Attach the aileron control horn using the hardware
provided (two long brass screws and a nylon backplate) and
fasten it in place using a small Phillips screwdriver.

15
Step 5. Repeat Steps 2–4 for the other aileron control horn.
Step 6. Locate the two threaded aileron wire linkages
(4-40 x 3 3/4"). Thread a jam nut and clevis at least 16 turns on
to each end of each rod. Be sure these are not the longer wire
control rods to be used later for the elevator.
Step 7. Install the clevis with the attached linkage to the aileron
control arm. Center the servo arm as shown. Make sure the
aileron is at 0° deflection. Hold in place with masking tape
if necessary.
Step 8. Do the same for the other aileron linkage.
Step 9. Attach the linkages onto their respective aileron control
horns.
Step 10. With the servo arm centered as shown, adjust the
aileron linkage until the aileron is exactly in the neutral position.
Follow this procedure for the other aileron linkage. Final
adjustments will be made later as you adjust the control throws
in Section 20.
Note: Be sure to fasten the metal clevis keeper to the clevis
as shown below. This will provide extra insurance against
the clevises accidentally opening.

Step 1. Locate the two dowels, nylon wing bolts, blind nuts,
wing bolt plate, and the tapered wing center plate section that fits
between the wing and front windshield former in the fuselage.
Step 2. Locate the shaped leading edge piece (wing center
plate) that goes in the wing and fits into the opening of the front
windshield former. Trial fit the wing to the fuselage to see if any
material needs to be removed from the tapered block so that the
wing will fit snugly onto the fuselage. Mix approximately 1/4 oz
of 6-minute epoxy and glue the shaped leading edge piece into
the slot in the wing as shown. Allow the epoxy to cure before
attempting to drill holes for the wing hold down dowels.
Step 3. Locate the two holes in the leading edge of the fuselage
front windscreen former. The holes have been predrilled in the
plywood former. Trial fit the dowels to make sure they will slide
into the holes without binding. When you’re satisfied, remove
the dowels.
Step 4. Use a ruler to mark the center line of the fuselage
opening where the trailing edge of the wing will rest on the
fuselage. We will use this mark to help center the wing on the
fuselage prior to drilling the wind bolt holes.

17
Step 5. Place the wing on the fuselage. The leading edge
should be centered on the front windshield former opening.
Note: There will be a small gap between the leading edges
of the wing and the fuselage sides, as shown below.
Step 6. Center the trailing edge of the wing center with the mark
made on the fuselage cabin area in Step 4.
Step 7. When you’re satisfied the wing is centered on the
fuselage, use masking tape to temporarily hold the wing in
position on the fuselage.
Step 8. With the wing secured, drill the dowel holes into the
shaped leading edge material you glued to the wing leading edge
in Step 2, using a 1/4" drill bit.
Caution: Do not drill through the leading edge material
completely, as you will drill into the square open wing skylight
area of the wing. We suggest using a piece of masking tape on
the drill bit to mark the depth you plan to drill.
Step 9. Remove the wing from the fuselage. Mix approximately
1/4 ounce of 6-minute epoxy and glue the dowels into the holes
in the leading edge of the wing you just drilled. Wipe away any
excess epoxy with alcohol and a paper towel. Allow the epoxy
to cure completely before attempting to reattach the wing to
the fuselage.
Step 10. Reinstall the wing and trial fit the wing hold down
plate to the trailing edge of the wing center. Note the rounded
portion of the plate faces toward the front. Mark the wing bolt
plate location on the wing with a felt-tipped pen or pencil.
Section 5: Mounting the Wing to the Fuselage

18
Step 11. Trim away the film covering the wing bolt holes in the
wing bolt plate. Next, trim the covering where the wing bolt plate
will be attached to the wing trailing edge top.
Caution: Use care in cutting away the covering, as cutting
into the balsa wood can weaken the structure.
Step 12. Mix approximately 1/4 ounce of 6-minute epoxy and
glue the wing hold down plate to the wing trailing edge top. Note
that the wing bolt plate has the holes already drilled out for the
wing hold down bolts. These holes will serve as the template
where the wing hold down bolt holes will be drilled into the wing
and fuselage.
Step 13. Carefully fit the wing into position on the fuselage
by first sliding the leading edge dowels into the fuselage front
wing dowel support bulkhead that makes up the frame for the
front windshield.
Step 14. Check the wing alignment at the rear with reference
to the centerline mark. Also, check the wing alignment by
measuring from each wing tip to the center of the fuselage tail
where the horizontal and vertical stabilizers are mounted. Use the
same point on each wing tip to make sure the wing is centered
on the fuselage.
Step 15. Once you’re satisfied with the alignment, you are
ready to drill the wing hold-down bolt holes through the wing
and into the fuselage wing bolt plate. Using a 1/4" drill bit and
the wing bolt plate holes as a guide, drill through the wing into
the fuselage and through the plywood wing hold-down plate.
Section 5: Mounting the Wing to the Fuselage
CONTINUED

19
Step 16. Press the blind nuts into position below the rear wing
hold-down block in the rear portion of the fuselage wing area.
One method is to use pliers with an adjustable opening to
squeeze the blind nuts so the "teeth" penetrate the wood and
stay in place.
Note: It's important that the blind nuts be fully pressed in
against the bottom of the wing hold-down block to make
sure they are properly aligned. This sets the alignment
angle of the wing hold-down bolts. It’s a good idea to place
a piece of wood on the top side of the wing bolt hold-down
block to keep from crushing the wood.
Step 17. A small drop of CA glue will help hold the blind nuts
in place. Use care not to get the CA on the inner threads of the
blind nuts.
Step 18. Fit the wing into position on the fuselage. Thread the
wing hold-down screws into the wing and loosely tighten them.
Check the alignment of the wing by measuring the alignment as
you did in Step 14. It may be necessary to slightly enlarge the
holes with a small round file to obtain the proper alignment.
When you are satisfied with the fit, tighten down the wing hold
down bolts.
Step 19. Locate the red wing center tape. Apply to the top of
the wing center section as needed.

Step 1. On the rear of the fuselage, slots are precut in the wood
structure for the vertical fin. The horizontal stabilizer mounts to
the area at the top of the fuselage rear. You will need to trim away
the covering with a sharp hobby knife.
Step 2. The horizontal stabilizer will be mounted to the
fuselage first. Keep the two elevator halves on the horizontal
stabilizer to assist in centering the horizontal stabilizer. Use a
straight edge to locate and mark the centerline of the horizontal
stabilizer. This will serve as a reference point when installing the
horizontal stabilizer onto the fuselage.
Step 3. By noting the centerline you marked, you can position
the horizontal stabilizer so that it’s centered on the fuselage
opening where the vertical stabilizer will go and the rear of
the fuselage.
Step 4. Mark the centerline of the rear of the fuselage. Position
the horizontal stabilizer so its center line mark is in line with the
fuselage rear mark. Use the ruler to make sure the horizontal
stabilizer projects an equal amount on either side of the fuselage
at that point.
Step 5. Install the wing and sight the horizontal stabilizer
alignment from the rear of the aircraft. Make sure the horizontal
stabilizer is level with reference to the wing.
